ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 7773360; dated December 13, 1904:.

Application filed May 21, 1904. Serial No. 209,057. (No model.)

To all who/7'1, it may concern.-

Be it known that I, WILLIAM VVYAND, a citizen of the UiiitedStates, residing at Oollingswood, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Rotary Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saline.

This invention relates to rotary engines or turbine-engines; and it consists in the novel is provided with a series of V-shaped chain bers at its periphery, and it is mounted on a shaft O, which is journaled in bearings c on the casing. In carrying out this invention the steam-wheel is not connected direct to the Shaft C.

D is a bush which is journaled freely on the shaft O and provided with a flange (l at one end, which runs against one of the bearings. The steam-wheel is provided with a hub E, which is mounted very loosely on the said bush D, so that there is a space between the said hub and bush. The hub and the bush are provided with opposed pockets and c,

. and F represents springs arranged in the said G is a driver secured on the shaft O inside the casing A. This driver is operatively con nected with the hub of the steam-wheel in any approved manner, so that the driver may be revolved by the steam-wheel and so that the steam-wheel is free to move radially to a limited extent in every direction. Any amiroved clutch mechanism 7 is provided for conuect- .ing the hub of the steam-wl1eel with the driver.

H is the steam-inlet passage in the casing, and 71/ represents two annular steam-chambers inside the casing which are connected with the said inlet-passage. These annular chambers are provided at suitable points with inclined steam-jet nozzles I, which project the steam into the steam-chambers of the wheel, and thereby cause the said wheel to revolve.

In order to use the steam with economy, re turn jet-nozzles J are secured inside the cats ing at suitable points. These return-nozzles have curved passages j, which receive the steam from the V-shaped chambers of the wheel on the opposite side from which it onters the said chambers from. the nozzles I and project the steam thus received into the V- shaped. chambers of the wheel at a point in advance in the direction of its motion. The steam finally passes out of the V-shaped chambers on the same side of the wheel as it originally entered and ills the free space inside the casing.

K is the exhaust or outlet passage through which the steam leaves the casing.

The steam-jet nozzles I are preferably provided with spiral guides 11?, which give the steam a whirling motion before it enters the steam-whoel. The spring-supported wheel adjusts its center of gravity automatically when it attains a high speed.

The clutch mechanism g preferably has two slidable friction blocks or segments 7, which engage with the internal periphery oi. the driver Or when thrown outward by centritugal force. These blocks have slots which cngage with projections 7t" on a collar which is mounted loosely on the shaft O, and the said collar has lugs a, which engage with slots in the end of the hub of the steam-wheel and permit the steam-Wheel to move radially in all directions on the shaft.

I/Vhat I claim is- 1. In a rotary engine, the combination, with a driving-shaft, and a steam-wheel mounted loosely on the said shaft and also free to move radially thereon; of a driving-collar mounted loosely on the said shaft and revolved by the said steam-wheel, a slidable friction-clutch member revolved by the said driving-collar,

and a driver secured-to the said shaft and rewise movable and slidable independent of each other, and a driver secured to the said shaft and revolved by the said friction-clutch member when the same is revolved rapidly.

3. In a rotary engine, the combination, with a driving-shaft, and a sleeve mounted on the said shaft and provided with pockets; of a steam-wheel provided with a hub also provided with pockets and free to move radially 0n the said sleeve, supporting springs arranged in the said pockets, a driver secured on the said shaft, and clutch mechanism between the said driver and wheel-hub.

In testimony whereof I have afiixed my signature in the presence of two witnesses.

WiLL'IAM WYAND.
